From .sigma.- to .pi.-bonding: crystal structures of (pentamethylcyclopentadienyl)triiodostannane and dichloro(pentamethylcyclopentadienyl)stibine [PDF]

Organometallics, 1992
Cyclopentadienyl compounds of the tetravalent group 14 elements and of the trivalent group 15 elements are characterized by their dynamic behavior due to migration processes of the relevant ElR, fragment. As shown by experiments and calculations, the energy difference between the [sigma]-ground state and the [pi]-transition state in these molecules ...

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...
